How to Perform ASTM C307 Chemical-Resistant Mortar, Grouts, and Surfacing Tensile Testing

Home / Testing Standards / ASTM C307 Chemical-Resistant Mortar, Grouts, and Surfacing Tensile Testing

Summary of Test

ASTM C307 is a testing standard that determines the tensile strength of cured chemical-resistant materials in the form of molded briquettes including mortars, brick and tile grouts, machinery grouts, and monolithic surfacings containing aggregate less than ¼ inches. Samples are mounted in a specific type of fixture, “tension clips”, and are pulled in tension.

Although these types of samples are not usually under tension when in service, the data obtained from a tensile test can be useful in determining the rate of cure and other properties.

Before conducting ASTM C307, it is important to read the entire specification in the relevant ASTM publication.

Recommended Equipment

Testing Procedure

  1. Prepare six test specimens for each material as described in the standard.
  2. Mount and center the specimen in the tension clips.
  3. Apply the load at the crosshead speed as specified in the standard.
